Finale-specific fixes

NotePerformer now uses key-switches rather than MIDI controllers for articulations in Finale, based on the fact that this is what Garritan’s internal sounds use. To the extent possible, NotePerformer’s choice of key switches also matches that of Garritan’s built-in sounds, which should make NotePerformer somewhat more immune to playback errors as a result of stray key-switches that are hard-coded into existing scores.

Slurs would sometimes initiate or end legato playback on the wrong note. Also, slurs ending on a staccato note would not always playback correctly. These problems have been fixed.

Doits and falls would sometimes play on the preceeding note instead. An error which could also make the articulation inaudible. The problem has been corrected.
